Subject: [PATCH 09/12] raid6test: adaptation with new syndrome function
Date: Wed, 12 Aug 2020 08:49:28 -0400	[thread overview]
Message-ID: <20200812124931.2584743-10-yuyufen@huawei.com> (raw)
In-Reply-To: <20200812124931.2584743-1-yuyufen@huawei.com>

After changing some syndrome and recovery functions to support
different page offsets, we also need to adapt raid6test module.
In this module, pages are allocated by the itself and their offset
are '0'.
